Marcelo Tibau , Sean Wolfgand Matsui Siqueira, Bernardo Pereira Nunes, and Pertti Vakkari https://doi.org/10.1177/0165551526147889 Abstract This study presents the degree of knowledge gain, a behavioral metric that estimates how much searchers learn during Web searches. Grounded in information theory and Shannon entropy, the metric quantifies reductions in uncertainty by analyzing query reformulations, clicks, and document positions, avoiding reliance on pre/post-testing or self-reports. The metric was validated with a cohort of […]
